IMPROVEMENT IN STAMPIHGTBESSES.

Be it known that we, ALBERT G. Mum and Cnnnnns J. ADDY, bothoiBosto'min the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in the Stamping-Presses which are naedfor stamping or embossing paper or other substances, of which the following is a ien, clear, and exact description, reference being had to the accompanying drawingm'mak ing part of this specification, in which Figure 1 is a longitudinal verticalcentrol section.

Figures 4 and 5 are horizontal plane sections on the line A B of fig; 2,

. Our invention consiets in the employment of a swivel-stop, a, which is seated in the annular hose B of the press, in combination with a s'wivel-die chuck, d, connected with the lower end of the slideA, or. to the stem 9 thereof; also in the'employmeutof a dog, f, applied to the chuckd, by means of a screw or ap'ivot, c, to engage with the stem of the slide, the hook-end e of-s'aid dog entering a socket mode in each side of the stamp, to prevent the slide turning when set fox-operation; also in the c nploymentnf a similar dog, 7:, applied to the top of the base, B, to engage with thsswivel-step a, in the same or in a similar manner; ehthlforthe same purpose springs c c are attached to the lever portion 7a of each of the dogs, to throw them into contact with their holding-seats.

The centre or pintle s, of the chuck d, enters the lower end of the stem of the slide, and is held up by a screw or a pin, 1, passing through one side of the stem g, into on annular groove made in the pintler', near its upper end, or between the shoulder a: and the end oi. the pintle. The step a may besecurod by the some means, v

or 'by a screw, 1:, passing upward from the chambered base into thc lower end of the step. A bar or lover',m, provides for turning or swivelling the stop a, and the phuck (2 may be turned or swivelled by pressing on tho lover-end of the dog f, which releases the hook-end of the dog from its holding-socket, and turns the chuck around when desired. A movable counter-block, p, is set into the top of the swivel-step, and the counter q is fitted into said block, the bottom resting on the stop a. The counter-block is connected with the stop byone ormore steady-pins, r, projecting downwardfrom the under side of the pluck, and entering holes in the upper side of the step. The lower portion of the swivel-chuck d may be connected with the upper portion, 8, thereof,

by a horizontal dove-tai1,-t, formed in one with the lower portion, and made to slide into the lock,'msde in the upper part to receive it. This 'dove-tnil makes the chuck reversible without the swivehsdjustment.

The slide A is fitted onto the head 0 of the stand, as shown in fig. 7, and ismoved vertically downward by a screw, 1), passing through the head 0 of the stand, the lower end of the screw having a step in th s lower part of the slide, above the stem 9. A spiral spring,'E, is arranged around the screw 1), between the top of the head 0 of the stand aud'tho under side of the cap F of the slide, to move the letter upward when the screw is turned backward, and upward to raise the slide and thoswivel-chnck d. Any other convenient device may be arranged to perform the ethos of the spiral spring. A bar or handle, -G,.connected with'the'top of the screw, is for turn-' ing the latter in either direction. I I p Our invention is designed for stamping or embossing the medallions or other figures on the corners of note= paper orletter-paper, and for stamping opombossing the some or similar figures, or the monogrnms, on the flap or fly of envelopes. The outlines of a small sheet of note-paper are seen in fig. and the outlines of an envelope are seen in fig. 5, and both in position on the counter q to receive an impression.

It will be understood that the figure or the monogram stamped on the corner of the note-paper is, .to use the common expression, right side up, but the figure or the monogram stampedpn the fly of the envelope must be bottom side up, in ;order tohave itproperly readablewhen the fly of the cnvelope is folded over.

. The stamping of the'figures on the envelopes could he done by turning the envelope around, the opposite side towords the operator, who should stand or sitin front of the press. But to make room'for. theongelope baolt of the conntor, the stand H of the press would have to be deeper, or extended back considerably, vwhich wouldnecessitnte a much henyier and stronger stand, and consequently a much. more ezpensive press By providing the swivel-step an'd the reversible or swivel-chuck, the figures or the monogroms may be impressed in or raised on the paper or other suitable substance, either side up, end with ease, facility, and econonly, and with a much lighter endless erpensire'press. The'liglit'er the'pr'ess, the easier and more rapidly i may be operated, consequently, the greater the amount'of work performed in a given time. 7

' It will be understood that the swivel-chuck has a mums, its lower end, to receive on impression-die, 4,

the face orlower end of which 'contoins the figures to be impressed on the 'paper or other substance, and the counter q being leatherl or guttai. porchn, or other similar and suitable substance, yields to the pressure of the die, and leavestho impression in or; on the. snbstancepressedor stamped, in the ordinary stumping-press.

In fig. 4, the swivel-stop sud the counters are rightside up, or the impression is readable from thc front of "the'press. In fig. 5, the swivel-step and the counter m shown as turned round half way, to bring the impression bottom side up, or readsblo by folding the fly of the envelope down, and by turning the envelope over endwsys, to sposition usually-held, to read the monogram. Infig. 6, the swivel-chuck is shown in two positions, either of whichpsitions msy he understood by the dogf on either sidcot' the figure, the lever-end I; of each pointing inoppositedireotions. .t t t i l i Our improvements msy'bo readily opplied'to almost any stamping embossing-press, or pressos intended for other purposes, and be made svailuble and very useful in such presses, and whether such. press is for stamping in ornamental design for artistic efl'ect, orfor any other kind of stamping or punching. A axnallcr ond lighter press may be mide to stamp or punch in, on, or through much larger articles or pieces than where the counter and step and the die-chnckore stotionory, or set for o'vertical motion, without the swivelliog or; revers iblo' adjuetment.

What we claim as now, had desire to secure by Letters Patent,.is--. a
